The body knows how to heal itself - it just needs to be allowed to do so. By continually encumbering the digestive system with normally too-heavy diets, the body is continually having to deal with the stuff that comes down the tubes – thereby not having enough time and resources to properly cleanse and heal itself.

     Among the many idioms with the word ‘heart’ are the two; ‘heavy heart’ and ‘light-hearted.’ Those idioms gain a literal application when applied to fasting. A successful cleansing fast will result in a light heart in the sense the heart physically feels lighter.  The first few days of a fast will likely thicken the blood, as impurities and fats get released. As the fast progresses, the blood should thin, as those impurities get released. The entire circulatory system will lose fatty deposits, so the thinner blood will move easier throughout. All these things contribute to a reduced burden on the heart – and the effects last beyond the breaking of the fast. Such improvements affect all parts of the body.
